Patent DE-3843923-A1 (DE)
Title: Method and apparatus for the unwinding of threads
Inventor: BROCKMANNS KARL-JOSEF DR ING
IPC: B65H59/04
Filed: 1988-12-24
Abstract: As is known, the thread pull during the yarn take-up increases, approximately in the last fifths of the bobbin run of a run-off bobbin, for example of a spinning cop, to a multiple of the thread pull which prevails at the start of the bobbin run. The most effective improvement is afforded by a drive of the run-off bobbin in the opposite direction of rotation to the rotation of the thread balloon, so that the relative speed between the balloon thread and the air is reduced. According to the invention, to improve the run-off behaviour, the run-off bobbins are driven pneumatically. The connection of the pneumatic drive is made as a function of a preset thread pull. The attachment mandril (13) of the run-off bobbin (2) is connected to a pneumatic drive (15). <IMAGE>

Title: Electrostatic processing of crude potash with no wet stage - using free fall separator in which vertical air flow is maintained
Inventor: SINGEWALD ARNO PROF DR
IPC: B03C7/00
Filed: 1989-06-28
Abstract: Processing ground mineral mixts. contg. a significant proportion of fines comprises first chemical conditioning, then triboelectric charging in carrier air, with sepn.  into coarse (C) and fine (F) fractions of specified size ranges. (C) is then processed electrostatically in a free-fall separator (FFS). (F), after sepn. from the carrier; is also treated in an FFS in which the electrical field is imposed on a flow of air passing vertically from the inlet to the base of the separator. The range of particle size sepn. is pref. 0.04-0.315 (esp. 0.063-0.2)mm, and the flow rate of the vertical air column is less than 3 (esp. 1) m/sec. The conditioned mineral is treated with heated air in e.g. a fluidised bed, using air of predetermd. relative humidity. The fines are removed in the air of predetermd. relative humidity.  The fines are removed in the air flow and recovered e.g. in a cyclone. The resulting fraction (particle size under 0.1mm) is passed to an FFS. USE/ADVANTAGE - The method is esp. applied to crude potash and provides sepn. according to both mineral type and particle size, i.e. sepn. of fines. It allows  complete dry processing of potash, eliminating the need for wet processing (which interferes with the dissolution process and greatly increases the amt. of waste liquor).

Title: Prodn. of liq. steel - from liq. iron oxide formed by treating metallic foam with high oil content etc., by mixing with pig iron
Inventor: KLIMANEK ERICH DIPL ING
IPC: C21C5/28
Filed: 1989-07-05
Abstract: Liquid iron oxide made by treating metallic foam having high oil or other impurifier is made directly into liquid steel by partially mixing with liquid pig iron in a converted process. The converter is filled just with liquid iron oxide and carbon and reducing gas used to reduce the melt and produces liquid steel. ADVANTAGE - The iron oxide is reduced by the carbon-rich pig iron and transformed into liquid steel. The converter is operated in the usual fashion with the blasting time being reduced as the liquid iron oxide initiates the carbon burning at an early stage. The blasting phase is also reduced which makes the oxidation of the accompanying element easier to control.
